ALFRED B. HUTOHINSON, OF BROOKLYN, NEWV YORK, ASSIGNOR TO THE GLEN COVE MACHINE COMPANY, (LIMITED) OF SAME PLACE.

WOOD-PLANING MACHINE.

SPECIFICATION forming part of Letters Patent No. 404,088, dated May 28, 1889. Application filed August 13, 1887. Serial No. 246,829. (No model.)

To all whom, it may concern:

Be it knownthat I, ALFRED B. HUTOHIN- SON, of Brooklyn, (Green Point,) in the county of Kings and State of New York, have invented a new and useful Improvement in Wood-Planing Machines, of which the following is a specification.

My invention in its entirety relates to wood-planing machines which comprise both an upper and under or lower cutter-head and side cutter-heads; but the several features of the invention may be embodied in machines which do not comprise all these cutter-heads.

I will describe in detail a planing-machine embodying my improvement.

In the accompanying drawings, Figure 1 is a side elevation of such parts of a wood-planing machine as are necessary to illustrate my invention. Fig. 2 is a longitudinalsection, and Fig. 3 a plan of the machine. Figs. 4 and 5 are respectively transverse sections upon about the planes indicated by the dotted lines :0 cc and y y, Fig. 3. Fig. 6 is a vertical section showing in detail a certain presserbar holder, a presser-bar and chip-breaker, together with their supports, employed in the machine.

here represented, and which are severally operated in the same way, the same letters of reference applying to each pair of feed-rolls and to the several parts which are employed in connection therewith. The several cutterheads are provided with journals, or have spindles which are supported in suitable boxes and are driven by belting in the usual way. The side cutter-heads, O, are upon side cutter-head spindles, O, which are journaled in the side cutter-head frames, 0 and these frames 0 are supported mainly by a bar, 0

.piece, D

here represented as round and extending transversely across the machine, the ends of said bar being supported in boxes 0 The lower portions of the frames O are steadied by a bar, 0'', and the frames 0 may, one or both of them, be adjusted laterally upon the bar 0 by the means usually employed. The lower feed-rolls, E, may be fitted in stationary boxes, while the upper rolls are journaled, as is usual, upon boxes 6, which are adjustable upward and downward upon roller-stands E in the well-known manner.

F designates what is usually termed the pinion-shaft of the machine, and which has a pinion, f, engaging a gear-wheel, F, which serves to impart motion to two wheels, F which are respectively upon the journals of two of the lower feed-rolls, E, and f designates an intermediate or transmitting pinion, which serves to transmit motion from one to another of two wheels, F thereby providing for the positive driving of the three lower feedrolls here represented. Each lower roll, E, is connected by lower and upper expansion-gears, 6 6 in a well-known manner with a gear-wheel or pinion upon the upper roll, E, and in this way the upper roll is driven, notwithstanding its adjustment up and down upon the roll-stand E.

I have in the drawings represented the gearwheels and pinions in whole or in part by dotted circles, as it is deemed unnecessary to show all their teeth.

The upper roll-boxes, e, which are on opposite sides of the machine, are connected directly and in a well-understood manner by rods 6 with arms e, which are upon a rockshaft, E and which insures the upper rollboxes upon opposite sides of the machine rising and falling simultaneously.

I will now proceed to a more detailed description of parts to which the most of my novel features relate. The lower cutterhead, D, which is at the delivery end of the machine, is supported in a cutter-head frame, D, as is usual, and on the front side thereof, or 011 the side on which the lumber enters, is a bar or mouth-piece, D while on the rear side thereof, or on the side on which the lumber is delivered, is a bar or mouth- The bar or mouth-piece D has in cross-bar D is constructed with downwardlyextendin arms D which are ivoted at d.

extending shaft,

below the cutter-head frame D, to the main side frames of the machine. The slots and bolts 01 d provide for adjusting the bar or mouth-piece D laterally toward and from the lower cutter-head, D, in a well-understood manner.

The bar-holder D may be vertically adj usted relatively to the cross-bar or yoke D by adjusting-screws (1 which are inserted through the ears or projections d upon the bar-holder D, as is best shown in Fig. 4, and which pass freely through holes in the bot toms of the pockets and bear upon shoes or cam-like surfaces (1 upon the cutter-head frame D of the machine, as best shown in Fig. 2, and also in Fig. 4:. It will be understood that if the bar-holder D has been by the screws raised away from the bottoms of the pockets (1 the bar-holder will fall slightly in the pockets as the cross-bar or yoke D is swung downward and away from the lower cuttar-head, D, as shown by the direction of the ar row in Fig. 2; but as these parts are returned or swung upward and toward the cutter-head the lower ends of the screws d will come to a bearing upon the projections 'or cam-like surfacesd, and will raise the bar-holder D to its normal position in the pockets. The bar-holder D may be kept from dropping out of the pockets, when it is swung downward, by a pin, (1 inserted laterally in the pocket and engaging an upright shouldered groove, (1 in the end of the bar-holder D, as best shown in Fig. 4, or by any other suitable means.

When the yoke or cross-bar D is swung upward to the position represented in Fig. 2, it may be held in that position and also drawn toward the cutter-head by means of horizontally-swinging yokes or clamps D' (shown in Fig. 3,) which are provided with clampingscrews d. I have also shown as secured to the crossbar D and its arms D by bolts (Z as shown in Fig. 2, an extension-table, D which is formed separate from the bar or mouth-piece D Above the lower cutter-head, D,is arranged a presser-bar, J. This presser? bar is supported near its ends by means of screws j, journaled in upwardly-extending brackets j which are hinged to the frame at 7' Upon the upper ends of the screws j are bevel gear-wheels 7' which mesh with other bevel gear-Wheels 7' mounted upon a horizontally- The shaft 7' has squared ends, which may be rotated to cause the raising and lowering of the presser J, as desired.

Ordinarily the boxes 0 which support the ends of the bar 0 are secured to the main side frames, A; but according to my invention I have represented them as secured by bolts 0 to the upright wall of the upper cutterhead bed B, as is best shown in Fig. 1, and accessible at the side of the machine. The bolts 0 pass through slots 0 in the cutter-head bed B, as is shown by dotted lines in Fig. 1,

but are accessible at the side of the machine,

an d after loosening them the boxes 0 may be adjusted upward and downward by adjusting-screws 0 between the boxes and the main frame, and which are also accessible at the side of the machine.

The upper cutter-head, B, is supported in boxes B which are adjustable upward and downward along slides B in the usual way, and which have brackets 12, to which is secured a holder B for a resser-bar and chipbreaker, As'best shown in Figs. 1 and 3, the presser-bar holder 13* extends across the top of the brackets b and is secured to them by screws 1), passing through slots 19 as best shown in Fig. 3. Thus the' adjustment of the holder B and the bar toward and from the upper cutter-head, B, is provided for. The ends of the bar and chip-breaker B pass beneath the brackets b, and the bar and chipbreaker are secured to the holder by bolts as best shown in Fig. 3. Both the holder B and the bar and chip-breaker B extend outward laterally beyond the brackets b sufficiently to receive an adj Listing-screw, 6 which is journaled so as to prevent its lengthwise movement in the end of the holder B, and is threaded to engage the end of the bar 13 as best shown in Fig. 1. Consequently when the screws 11 are loosened (their holes beingslotted) the screws 19 may be readily reached at the side of the machine without extending the arm over the moving parts and into out-of-ther' way places, and without inconvenience or danger the bar or holder may be raised or lowered relatively to the work.

I have represented the shafts of the expansion-gears e e as supported by a braeket,E

below the lower hub the bracket extends in-- ward toward the lower roll, and, as here shown, slightly downward, the end being pivoted at e in the roll-stand The upper end of the bracket F." is supported by a swinging link, E which is pivotedconcentric with the journal of the upper roll, E, it being here shown as pivoted upon the upper roll-boxes, e.

The letters of reference which are applied to the expansion-gears and their appurtenances apply equally to each pair of feedrolls, the construction being the same.

to form the bearing for the shaft of the lower expansion gear, 6', directly in the roll-stand E and consequently the shaft has had to be removed endwise before the expansion-gears could be removed. It will be seen here, how- One construction heretofore employed has been ever, that by simply withdrawing the pivot e and then slipping the eye of the link E off from the upper hub of the bracket E the bracket and its two expansion-gears may be easily withdrawn and removed. I have here shown each pair of feed-rolls as provided with an adj Listing-screw, G, having at the top an operating-handle, .g, and journaled at g in the top of the roll-stand E in such manner as to provide for its lengthwise movement upward, or in one direction, as best shown in Fig. 5. As here shown, the threaded portion of this screw directly engages the upper roll-box, e, as best shown in Fig. 5, and to this screw are applied the weighting-connections for holding down the upper roll with a yielding force. In the case of the two pair of feed-rolls, which are at the feeding end, or the right-hand end of the machine in the drawings, I have shown two screws G as connected by a cross-bar or yoke, G, and a link or rod, G with a weighted lever, G but in the case of the last pair of feed-rolls, which is adjacent to the lower cutter-head, D, and near the delivery or lefthand end of the machine,I have shown the screw G as connected by a hanger, G with the weighted lever G It will therefore be seen that through the screws G the weighting-connections apply their force to the upper roll-boxes, e, and their roll, and when the lumber passes into the machine the screws are free to rise with the roll and roll-boxes as the weighting connections are overcome. By shifting the screws G the upper roll-boxes may be raised or lowered to a definite degree. It will be seen that the adjusting-screws G, being arranged in the roll-stands E and not on the outside thereof, are out of the way,

while they are readily accessible from the side of the machine, and by engaging the screws directly with the upper roll boxes other connections which have heretofore been employed are dispensed with.

-What I claim asmy invention, and desire to secure by Letters Patent, is
